Hollow Grind Calculator

The Perplex of Convex


The discussion comes around every once in a while about wheel diameter to stock thickness and how high a concave or hollow grind will be. Some time ago Bimjo published a web based calculator for this based on Rob Frink's formula. Bimjo's widget seems to have disappeared from the web, but some Wayback pages can be found. Using the same formula I made a new online version.


The idea is that you choose a wheel diameter and some steel thickness and lastly the edge thickness. The calculation is done and you receive the height of the grind. Link is here: http://dcknives.com/public/grind_angle_concave.php
